Also Trying to understand takeouts on flanges using this app is difficult as well. So far that’s all I used this app for to find out they got wrong info. Will reply back if I see anything else wrong. ### 3/5 — Stopped working *2013-04-10, version 1.65* Is an excellent app when it is working, but for some reason it does not open anymore ### 2/5 — Fix it *2012-04-18, version 1.61* There's more than just welders in the USA either fix it or refund 10 bucks come on buddy if u Gunna charge that make sure it works uh ### 3/5 — Needs fixing *2012-01-24, version 1.61* Not bad data but it crashes when you tap the unit screen. Should be fixed before more people shell out the near $10 for a faulty app. ### 3/5 — Not too bad *2011-09-13, version 1.61* Good app but no data past 24"? I'm trying to build the oil sands not plumb my house. Please update with sizes up to 36" at least. Paid good money but I won't put 5 star until 36" data is present ### 3/5 — Lil help *2011-04-20, version 1.61* Needs flange size reference to the size of studs , nuts an wrench sizing chart like a pipefitters paperback handbook. Other then that very good. But lacks a few things. ### 3/5 — Not bad *2011-04-12, version 1.61* Cool to show off to the boys. But not worth the money! ### 4/5 — Handy *2011-01-19, version 1.6* A handy reference but flanges could do with PN listings also... That's why I only gave 4 stars.. Maybe a thought for any future updates ### 2/5 — Journeyman Pipefitter *2010-05-21, version 0* When I first got the app it was okay. It hade some usful info like weight/ft on pipe. But now since I down loaded the new version it keeps taking me back to my home screen. I open it, select the new threaded tab and bam I'm back to my home screen. For 8 bucks you would think you would be able to use it on the job, you can with paperbacks. Unless they fix the problem I would not recommend to anyone. ### 4/5 — Awsome app *2010-03-25, version 0* Works awsome but needs the sch. of the flanges for weight and etc. ### 1/5 — Last Update has stopped this working *2010-03-01, version 0* Was a great app prior to last update today. Now when i press start it closes out and returnes me to app screen. Add this to the fact that when i try to get support the support page cannot be found?????????????? ## Most critical reviews (10 lowest-rated) ### 1/5 — Inaccurate flange weld neck sizes *2025-01-28, version 1.82* Don’t buy. First time I went to use it I had to check my handbook and was way off ### 1/5 — App no longer works *2013-04-09, version 1.65* Latest update has totally crashed the app! Please fix asap as it worked perfect before!! ### 1/5 — Keeps crashing won't open after sending me software update!!! *2013-04-09, version 1.65* Sort it out ### 1/5 — Not working anymore *2013-04-08, version 1.65* The new update just killed the app on iPhone 4s 5.11. Please fix....... ### 1/5 — What's happened???? *2013-04-07, version 1.65* App doesn't open at all since last update. Please fix ASAP!!!!!! ### 1/5 — Not working *2013-04-07, version 1.65* This latest update makes this app unusable. Hope there is another update very soon because the previous version worked fine. ### 1/5 — Update *2013-04-07, version 1.65* I just updated this app and now it won't even run??? ### 1/5 — Ok for quick reference *2011-09-12, version 1.61* Not all measurements are correct for fittings. Make sure to double check before the issue for construction goes out. Don't bother with this app, it just doubles your work due to inaccuracies. ### 1/5 — Not worth a penny *2011-08-13, version 1.61* Do not pay for this app. It don't work like app store says. It shows no stud or nut info at all and goes back to home screen on your phone when you tap on certain parts of the app ### 1/5 — Not worth the money *2010-03-25, version 0* what exactly is it? a reference data sheet or calculator as there is no calculator! 4.99 down the drain...pardon the pun ## Most praised reviews (10 highest-rated) ### 5/5 — Better than ever *2013-06-03, version 1.75* I had issues with the newest update not booting up on my iPhone 4. I contacted tech support and was told the following; "It does work. For whatever reason you need to open and close it twice during the first run." I did what he said and the app works flawlessly now and looks better than ever. Very handy app for takeoffs on the fly. ### 5/5 — Where's the valve info? *2012-09-26, version 1.61* This app works great! If you do the delete and reload work! I'm not so patiently waiting for the valve info! ### 5/5 — The best I've seen-a must have *2010-09-25, version 0* This is by far the most complete pipe fitting app out there. I haven't checked the dimensionals yet but expect that to be as accurate and detailed as the program. The only thing I can see that needs an improvement is under threaded fitting, sure would be nice to see threaded pipe couplings added. You have the couplings under the socket welding but not in the threaded selections. Still a 5 star. Thanks. ### 5/5 — Excellent *2010-06-12, version 0* I can't say enough good things about this app. It truly is indispensable on a day-to-day basis. The amount of invaluable information contained in it is amazing and yet we are promised more updates!!!??? In a word, EXCELLENT!!!!! ### 5/5 — Pipe fitter Handbook *2010-03-02, version 0* This app is very handy works well and very easy to use. looking forward to new updates to this app! ### 5/5 — Brilliant! *2010-02-24, version 0* As an apprentice fabricator/welder this is an indispensable app. Awesome ### 4/5 — Great app *2014-01-16, version 1.75* Need to update add all pipe valves but overall great app ### 4/5 — Need bigger size flange *2011-07-29, version 1.61* Flange size stop at 24", PLEASE put data for bigger size flange. Other than that pretty good ### 4/5 — Stud Torque? *2011-03-23, version 1.61* Great app! Would be great to have stud torque in the flange section. ### 4/5 — Useful could be better *2011-02-13, version 1.6* Would have had 5 stars but the Elbows section has no Sch 10s or Sch 20 where applicable. Agree with the other comment "PN" flanges would make a useful addition. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
